BRICK-MACHINE.

PECIFICATION forming part of Letters Patent No. 390,110, dated September 25, 1888.

Application filed August 18, 1887. Serial No. 247,276.

To all whom it may concern.-

Be it known that I, ROBERT A. WrLLn'r'r, of South Amboy, in the county of Middlesex and State of New Jersey, have invented a new and Improved Brick-Machine, of which the ollowing is a full, clear, and exact descrip- Reference is to be had to the accompanying drawings, forming a part of this specification, 1n which'si'milar letters of reference indicate corresponding parts in all the figures. I

Figure 1 is a broken plan view of my new andimproved brick-machine. Fig.2 is a side elevation of the same, the lever being partially broken away. Fig. 3 is a sectional elevation taken on the line xxof Fig. 1. Fig. 4 is a transverse sectional elevation taken on the l ne y y of Fig. 3. Fig. 5 is a detailed sectional view of the two main power-levers, the cams and connections for operating them, the molds, and plungers. Fig. '6 is a detailed view showing the mechanism for operatingthe uptake.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

A A represent the main frame of the machine, and B represents the main power-shaft,

The clay is fed to the molds E from a hopper, H, (see Fig. 3,) by a sliding feed-box, J, which is reciprocated from a position in line with the bottom of the hopper to a position immediately over the molds E by means of a connecting-rod, J and crank J, secured to the shaft J, which is rotaril y reciprocatcd, as hereinafter described.

The lever K is for reciprocating the uptake M. It is placed loosely upon the shaft J, and

(No model.)

is connected to an arm on the uptake by a connecting-rod, K", and is reciprocated by the cams L L, secured to the spokes of the wheel 0, (see Fig. 6,) acting upon the lever L, which is connected to the arm K of the said lever K by the connecting-rod K*. The downward movement of the lever L will thus swing the uptake M to the position shown in Fig. 3, while the upward movement of said lever will permit the uptake to drop to the position shown in Fig. 2.

The uptake M is secured to the heavy shaft M and actsin connection with the upper plungers, F, and the cross-bar F, to which they are attached, and its object will be fully explained below.

The lower plungers, G, are attached to the crossbar G, which rests in the center upon the heavy spring G which normally holds said cross-bar and plungers somewhat elevated from the saddle-pieces g g, as shown in Fig. 2, until the plungers F are let down on the material in the molds E. Then the loose bar G is driven down into the saddles g g by the descent of the upper power-levers, P, so that said spring will take the first and second pressures applied to the brick material in the molds,which first pressure settles the material and partially excludes the air and fits the material for the following heavier pressures.

The saddle-pieces g are held at the bottom of the heavy yokes N at each side of the machine, which yokes depend from the heavy levers O O, and the saddles g are made vertically adjustable by the wedges g g, for making bricks of different and uniform thicknesses. The wedges g g are adapted to be moved by screws gig shaft 9, pinions g, and worms 9 and hand-wheel 9, so that the adjustment can take place without stopping the machine.

The heavy levers O O are fulcrumed at their forward ends upon the fixed studs 0, and the upper heavy levers, I, are connected to the heavy links or connecting-rods O O, which are connected to the studs O and constitute swinging fulcrums of the levers P. The levers P act upon the heavy shaft M, which shaft is free to move vertically through a short space in slots in the main frame, and the downward movement of this shaft forces thecross-piece F and the upper plungers, F, downward for IOO effecting the heavy final pressure upon the brick material in the molds. The levers O are operated by the cams O, secured upon the shaft D, while the upper levers, P, are operated simultaneously at the final pressure with the levers O in the opposite direction by the heavy cam P (See Figs. 1 and 5.) The said cam I is secured on the shaft D and acts upon the sliding frame 1?", which is connected to the two levers 1 by the heavy cross-piece P" and shaft 1" and forces the levers P downward. The said levers I are lifted by the cams P on shaft D acting against the rollers (Z, secured to the frame I, as shown in Fig. 8. Before the ascent of the levers 0, permitted by the cams O, the upper plungers, F, are brought down, by means hereinafter de scribed, on the clay in the molds E to give the material its first or initial pressure. Then the levers P are dropped down on the plungers F, giving the second pressure to the ma terial. Their weight then drives the crossbar G down into the saddle-pieces g 9, giving the third pressure to the material. Now the levers O are operated by the cams 0, thereby lifting or tending to lift the upper levers, P, up by the material in the molds, imparting another pressure to the now partly-formed brick. The air is now thoroughly expelled from the clay, and the brick receives its final pressure by the cam P pulling the levers 1? down, and the cam O holding the lever O in the position shown in Fig. 5.

As above stated, the upper plungcrs, F, are connected to the cross-piece F, which is held in slots in the main frame, and at the time of the discharge of the completed bricks and the recharging of the molds the said cross-piece and molds are elevated by the levers F", and this upward motion must be considerable to admit the feed-box beneath the plungers. The levers F are connected to the eross piece F by the links F, and are attached to the shaft F",whieh is rotarily reciprocated by the lever F", acted upon by the cams F attached to the wheel 0.

In order to avoid the necessity of lifting the heavy shaft M the distance required to clear the plunger-s F from the feed-box J, I employ the uptake M, which, when the said plungers are lifted, is swung outward to horizontal position, as shown in Fig. 3, by the action of the lever K, as above described. The uptake remains in this position until the cross-piece F and plungers F reach the clay in the molds on the downward movement caused by the levers F F and cams F At this time the uptake is turned to vertical position by the movement of the lever K, as shown in Fig. 2, where its lower edge rests upon the upper surface of the cross-piece F. At this time mold-boxes.

catcd at the proper time by the cams L and connections K, K",l.(",and L,as shown clearly in full and dotted lines in Figs. 2 and 6. The bricks, after being com pressed in the mold boxes E,are expelled by an upward movement of the lower plunger-s, G, and cross-bar G, produced by the lever Q, fnlcrumed on shaft Q, said lever being acted upon by the cams Q, on the wheel G to raise the plungers G to a level with the top of the molds E. (SeeFig. 1.) At this time the lilling'box J is moved forward to till the molds again,and this move ment of the filling-boxes shoves the bricks out upon the table T. The feed-box J is reciprocated from the shaft D by the two opposite cams J J" acting through the yoke J lever J, connecting-rod J", and arm J".

The quantity of material taken in the molds E is regulated by the eccentric T, (shown in Figs. 3 and 4,) secured upon the shaft T beneath the spring G The shaft T may be turned for causing the eccentric to lessen the drop of cross-bar G and plunger G, thereby increasing or diminishing the amount of clay in the molds E at Will.

It is Well known that certain qualities of clay may be worked very rapidly, while others require a very slow pressure to produce the best results. In order to adapt the pressure to the different qualities of clay, I attach to the cams P the segments U, (shown in Fig. 5,) which retard the yokes P and levers P in their descent, and thus cause a slow downward movement of the plungers in the mold-boxes. By removing these segments the instant the points cl of the cams pass the rollers cl the yokes P and levers 1? drop and instantly compress the clay; but when the segments are used the curved outer edges thereof support the yoke and cause a slow downward movement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The COll'lblllZllllOll, with the power-levers and shaft M, of the uptake M, means for reciprocating it, and the eross-piece F and plungers F, substantially as described.
